Asymmetric-pole single-phase doubly salient permanent magnet machine (APSP-DSPMM) can yield higher torque and lower dead zone than the traditional one. Some special structural factors, such as the stator pole pieces, unequal air-gap lengths, and seriously saturated auxiliary teeth, if not properly considered, may bring large errors in the electromagnetic performance evaluation. This article proposes an improved magnetomotive force-specific permeance method to account for these special structural factors. This method is implemented numerically to obtain the electromagnetic performance of APSP-DSPMM under the conditions of no-load and full-load, and the results are compared with those of the two-dimensional finite-element analysis. The theoretical results are verified by the experimental test results of a prototype.
